Arabic volute

Arabic volute. Several ploughing through the mudflat at low tide. Haven't seen these before in the intertidal zone.

Extremely large [for NZ] volute. Aperture area looks quite fresh but spire shows serious deterioration, and the common fixing of iron oxide is evident in the shell. I wonder just how old this animal was when it perished. Many decades, I'll vouchsafe, and been on the pension for several of them!

Lacks the pinched and pointed armor of A. arabica ss, but still very strong shells. Was known as A. larochei but it seems has been relegated to another form of S arabica. I'm never sure with this genus, there seem so many mid forms. Some taxonomist have taken the time to identify these as subspecies of something, then the lumpers have thrown them all together again. I give up! They are Volutes in my vocabulary, the whole lot of them. Sometimes 'common' names are just great!

A. arabica forma depressa . It has a much blunter spire and does have raised 'spikes' like A. arabica but perhaps not quite as sharp. Takes it's name from the depressed spire.

I think these are juvenile Alcithoe, but one thing concerns me, the protoconch area is too broad and blunt for most species excepting perhaps Alcithoe albescens. No half or full grown specimens of that were present on the beach, and these were all pretty much the same size. All bit of a mystery.

I think this is Alcithoe seelyeorum (knobby form) but that is not in the database so I am probably wrong! *LOL* And also not found in the area that it apparently is, although the currents come thorugh here (ref http://www.nzshells.net.nz/Images/2115H.jpg) However, I chose Arabic Volute as there was one found on the Karikari penninsula which is just across the ways.
